At present, the laser marking machines in the market include fiber laser marking machines, ultraviolet laser marking machines, and carbon dioxide laser marking machines, and the more widely used laser marking machine models include fiber laser marking machines and UV laser marking machines. And the two are often confused and compared. In fact, not only the lasers are different, but also the working principle is completely different, and the price is also quite different. Let's follow Suntop laser today to understand the comparison of advantages between fiber laser marking machine and UV laser marking machine.
1. Advantages of fiber laser marking machine
· Good beam quality
The laser beam is thin, the processing material consumption is small, and the processing heat-affected zone is small. The markings on the markers are permanent and will not fade from environmental influences. The marked graphics are exquisite and beautiful.
· long lasting
Fiber laser technology can greatly extend the service life of the equipment, up to 100,000 hours.
· Energy saving and environmental protection
The electro-optical efficiency of the fiber laser marking machine is as high as 28%, which greatly saves power consumption during work, saves operating costs, and is pollution-free and noise-free.
· Low maintenance cost
Since the fiber laser has no optical lens in the resonator, it has the advantages of no adjustment, no maintenance, and high stability, which is unmatched by traditional lasers.
2. Advantages of UV laser marking machine
· Capable of ultra-fine marking and special material marking
Due to the extremely small focus and the small processing heat-affected zone, the UV laser can be used for ultra-fine marking and marking of special materials. It is the first choice for customers who have higher requirements for marking effect.
· The effect of cold working method is better
UV laser is cold processing, because the high-energy molecules of ultraviolet photons directly separate the molecules on the metal or non-metal materials that need to be processed. However, this separation causes the molecules to separate from the material. This way of working does not generate heat.
· No burning of materials
The heat-affected area of the UV laser marking machine is extremely small, it will not produce thermal effects, and will not cause the problem of material burning.
· Low power consumption
Ultraviolet lasers are mainly low power, with stable performance, small size and low power consumption.
Just because the advantages of fiber laser marking machine and UV laser marking machine are different, their application scenarios are also different, and the choice of laser marking machine will also be different.
Fiber laser marking machines are widely used in integrated circuit chips, computer accessories, industrial bearings, watches, electronic communication products, aerospace devices, various auto parts, home appliances, hardware tools, molds, wires and cables, food packaging, jewelry, tobacco , military, etc. on-site graphic marking, batch production line operation.
UV laser marking machine: especially suitable for the high-end market of fine processing like:
1. The surface marking effect of polymer material packaging bottles such as cosmetics, medicines, and auxiliary materials is good, and the cleaning power is strong, which is better than inkjet coding and pollution-free;
2. Marking and scribing of flexible pcb boards; processing of micro-holes and blind holes on silicon wafers;
3. LCD liquid crystal glass two-dimensional code marking, glassware surface drilling, metal surface coating marking, plastic buttons, electronic components, gifts, communication equipment, building materials, etc.
